Finally managed to make the brackets for second alternator, I found that mounting it on the power steering pump didn't tension the belt. Took several attempts to find the wright bracket design.

Re: Second alternator and battery for winch

Matt, Nacho001 on here, did a twin alternator on one of his trucks, pretty sure there's a build thread somewhere.

Re: Second alternator and battery for winch

If it's the thread I read then the install was never completed, I did try it but could not get the drive belt to tension. So i started from scratch. I ended up mounting a bracket on the side of the engine useing two convenient taped holes. I also had to do some work with the steering pump pipes,

Re: Second alternator and battery for winch

Hi nacho001, when I tried to mount my alternator in the way you show I couldn't get the belt to tension properly.

Re: Second alternator and battery for winch

The power steering pump has the ability to be used to tension that belt.When used without AC or 2nd alternator, it is used to tension the belt that runs it alone from the crank.

It would however require for the 2nd alternator to be mounted independent of the steering pump for this to be most effective.Inclusion of the alternator on the same bracket would probably exert to much leverage with the pulley that far from the pivot point.

I successfully used it in this instance to provide tension, although it did take me a few attempts to get the correct length belt to use.
